Up to four switch contacts allow all desired switching functions to be completely
covered. Depending on the application requirement, falling closing, falling opening,
rising closing or rising opening can be switched.
The switch contacts are adjusted for either falling or rising density.
It is recommended to always switch only in the switching direction adjust-
ed ex works, since otherwise the switch hysteresis of the switch contact
also has to be taken into account.
→ Detailed information regarding hysteresis see data sheet SP 60.27
Examples for switching functions in the application
